We excavate only where necessary and restore landscaping as part of the scope.

Exterior work only pays off if the membrane, footing drain, and grading are all addressed together — fixing one without the others often leaves the underlying pressure problem unresolved. We scope the full picture before recommending excavation.
We call in utility locates before any digging starts, standard on every Grenloch, NJ exterior job.
Weather-dependent scheduling means we plan exterior jobs around Grenloch, NJ's rainy season windows when possible.
Pricing is quoted per linear foot of foundation wall being treated, based on an on-site measurement, not a phone estimate.
We install dimpled membrane rated for below-grade use, paired with a footing drain that ties into your existing or new drainage system.

Every Grenloch, NJ Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
This is the most comprehensive Grenloch, NJ waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.
We slope footing drains correctly during installation, since a flat or reverse-sloped drain simply won't move water.
We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.
We also inspect and reseal the window frame itself while the well is open.
Downspouts discharging within a few feet of the foundation send roof water directly toward the problem — we extend them well clear of the wall.

We ask about grading, downspout placement, and where interior water is showing up to narrow down the likely exterior cause.
A technician walks the exterior perimeter, checks grading slope, and identifies where excavation would be needed for a membrane or footing drain fix.
We explain what's included in landscaping restoration so there's no confusion after backfill.
Excavation, membrane installation, and backfill for a typical residential wall section usually take a few days depending on access and weather.

"Membrane and footing drain install took three days but the wall that used to weep every storm has been bone dry since."

"They found our downspouts were dumping water two feet from the foundation. Extended them and regraded, and that alone made a noticeable difference."
— Grenloch Customer
"Appreciated that they called in utility locates before digging near our gas line."
— Grenloch Homeowner
"Fast turnaround given how much digging was involved."
— Grenloch Customer
We'll recommend the right approach based on what the inspection actually finds.
Some disruption is unavoidable near the foundation, but we restore grading and replant where reasonable as part of the scope.
We measure your specific foundation during the on-site inspection rather than assuming a standard depth.
We'll walk through both options and their trade-offs so you can make an informed choice.
Yes — grading correction and downspout extension are often standalone fixes that resolve a surprising number of Grenloch, NJ water intrusion issues on their own.
Larger projects or difficult access points can extend the timeline, which we'll outline in the written quote.
